An Exploratory Randomized Controlled Study of Arthroscopic Inlay Bristow Procedure for Recurrent Anterior Shoulder Dislocation

Overview

To evaluate the clinical and radiographic outcomes of arthroscopic inlay bristow procedure in treating recurrent anterior shoulder instability.

Aim: To compare the clinical and radiographic outcomes following the arthroscopic Chinese Unique Inlay Bristow (Cuistow) procedure and the arthroscopic Bristow procedure. Background: The Cuistow procedure is a modified Bristow surgery in which a Mortise and Tenon structure was added to the contact surface between the coracoid tip and the glenoid. In previous retrospective study, patients received Cuistow procedure have satisfying clinical performance and excellent postoperative bone healing rate (96.1%). However, no prospective randomized controlled trial was performed. Methods: 70 patients with recurrent anterior shoulder instability were included and randomized to either an arthroscopic Cuistow procedure or arthroscopic Bristow procedure. Radiological evaluations with 3D CT scan were performed preoperatively, immediately after the operation, and postoperatively at three months and during the final follow-up (more than 2 years). Clinical assessment for a minimum of 24 months including the 10-point visual analog scale for pain and subjective instability, University of California at Los Angeles scoring system (UCLA score), American Shoulder and Elbow Surgeons score (ASES score), ROWE score, Subjective Shoulder Value (SSV) and active range of motion were completed by independent observers and analyzed.
